Alkylated, benzylated and bromoalkylated benzimidazole-thione that intramolecularly heterocyclized to 3,4-dihydro-2H-[1,3]thiazino[3,2-a]benzimidazole were synthesized. The chemical structure of the synthesized product was characterized by Infra Red, ¹H-NMR, (13)C-NMR, and Mass spectroscopy. Furthermore, the molecular structures of 8 and 9 were confirmed by X-ray single crystallography in diffe...

Reflectance and emittance spectroscopy in the near-infra red and short-wave infra red offers a rapid, Inexpensive, non-destructive tool for determining the mineralogy of rock and soil samples. Hyperspectral remote sensing has the potential to provide the detailed physico-chemistry (mineralogy, chemistry, morphology) of the earth’s surface. This information is useful for mapping potential host r...

Multispectral acquisition improves machine vision since it permits capturing more information on object surface properties than color imaging. The concept of spectral filter arrays has been developed recently and allows multispectral single shot acquisition with a compact camera design. Due to filter manufacturing difficulties, there was, up to recently, no system available for a large span of ...

In order to determine mineralogy of rock and soil samples, reflectance and emittance spectroscopy in the near-infra red and short-wave infra-red is used extensively and found to be inexpensive. Hyper spectral remote sensing satellite data are found to be prospective to deliver in depth physico-chemistry like mineralogy, chemistry, morphology of the earth’s surface. Therefore hyper spectral data...

Abstract Large magnetic optical rotary dispersion (Faraday rotation) has been demonstrated recently in methylammonium lead bromide. Here, we investigate the prospect of extending active spectral range by altering halogen. We also origins large Faraday rotation these diamagnetic materials using circular dichroism (MCD) spectroscopy and Kramers–Kronig relations. find that, while MAPbCl 3 (MA = me...

Nonlinear excitation of fluorophores through molecular absorption of two or three near-infra-red photons from the tightly focused femtosecond pulses of a mode-locked laser offers the cellular biologist an unprecedented panoply of biomolecular indicators for microscopic imaging and cellular analysis. Measurements of the two-photon excitation spectra of 25 ultra-violet and visible absorbing fluor...

PHOTOGRAPHY WITH INFRA-RED FILM Dekking (1933, 1934) published several photographs of eyes with dense corneal opacities using infra-red film and radiation of a wave-length of about 10,000 A.u. His photographs strikingly demonstrated how infra-red radiation could penetrate a dense corneal opacity, and clearly record the appearance of the iris and pupil, which were invisible by ordinary methods o...

The TiO 2 /MXene composites prepared by different routes were assessed towards the degradation of organic pollutants under simulated solar light. A notable photocatalytic activity bare MXene near infra-red light was discovered.
